Meaning of Aperture problem

Aperture problem given a sequence of images over time we would like to infer the motion (optical flow) field. Based on local image information (i.E., Based on the values of those pixels falling within some aperture) only the component of motion along the graylevel gradient can be inferred, that the component of motion perpendicular to the graylevel gradient can only be known by resorting to global methods is known as the aperture problem. See optical flow, optical flux.
